Application August 3, 1934, Serial No. 738,267 Renewed August 28, 1935 8 Claims. (Cl. 132-82) The invention relates to holders for retaining powder or similar material in loose form, and more particularly to the closure element or top associated therewith and through which the retained powder is to be dispensed.

'I'he invention has for an object the provision of a simple and effective closure member of this nature which may not only serve for convenient removal of the powder from the container but will enable such closure member or top to be readily applied to the open end of the container and to secure a proper closure thereat.

A further object of the invention resides in the provision of a closure member which may be inexpensively constructed and which is readily manipulated in the dispensing of the container contents; and when not in use serves adequately to prevent spilling of the powder contents.

Still another object of the invention resides in the provision of a closure member adapted for use with a container element constituted of elastic material, and requiring` no cements or adhesives for securing the member thereto.

In the accompanying drawings, which illustrate the invention in several of its preferred embodiments, Fig. 1 is a part elevation and part vertical section illustrating the novel closure member as applied to a powder container.

Fig. 2 is a plan thereof, with cover removed.

Figs. 3 and 4 are plan views respectively ofthe cover element and of one of the clamping plates.

Figs. 5 and 6 are similar views respectively of the associated clamping plate and of a screen held therebetween.

Fig. '7 is a part front elevation and part vertical section illustrating a modied fo-rm of the closure member.

Fig. 3 is a plan thereof.

Figs. 9 and 10 are plan views of the associated closure elements, the element shown in the latter view also constituting one of the clamping elements; and Figs. l1 and 12 are plan views respectively of the other of the associated clamping elements and of a screen held therebetween.

Referring to the drawings, Hi designates a container for powder, said container being preferably of the nature of a loader element designed to be fitted within a cylindrical box II or other receptacle. It is preferred to construct this container of elastic material and in the form more or less of a bellows, for example as is more particularly set forth in my Patent Number 1,999,227, April 30, 1935.

The container as thus disclosed is constituted of elastic or resilient material, such as rubber,

yand is of thefdesired contour and preferably provided with a series of circumferential corrugations or folds I2 forming a bellows or like collapsible member thereof.

In accordance with the present invention, f provision is made for securing Vto the uppermost fold I3 of the container a closure member constituted of a pair of metal clamping elements or plates between which the fold I3 maybe securely held.

Thus, a clamping plate or annular disk I5 is associated with a. similar clamping plate I6, and each plate provided with an aperture I'l and I8, respectively, adapted to registerV when the plates are superposed for vthe purpose .hereinafter set forth. The plate I5, furthermore, is provided with a depressed seat or inwardly extending flange I9 designed to receive a screen or strainer 2li, this .screen being Aheld in place firmly bya depressed inwardly extending flange `2I of the plate I6 resting thereon when the `plates are superposed, as indicated in Fig. l1 of the vdrawings.

In this position, also, the two said plates vare designed to receive and hold between 'them 'the inner edge or fold I3 ofthe container, andthe union is insured by turning under the said fold a plurality of 'outwardly'extending and bendable spurs or tabs 22 extending loutwardly from the. edge of the Vuppermost plate I6. These tabs are bent over and vclamped tightly toward the .uppermost plate to compressor pinch the said 'edge of the resilient material constituting the container with sufficient force to prevent 'normally removal of the said plates which thus form a 35 supporting frame for a closure .element which may be variously cpnstituted.

For example, as indicated in Fig. V1 of the drawings, the cover element 26 designedifor closing the aperture I8 is constituted as a circular 40 disk 21 'having 'an upper rim or flange 2'8, the disk being adapted to seat on the flange '2I with its flange 28 overlapping. The vsaid ange 28, furthermore, is hinged to the outer end 29 of a bar 3E! adapted to extend diametrically over the 45 outer face of the disk, the said bar being hinged at its opposite end A3| tothe annular superposed plate I6 and thus attaching the said cover element thereto.

When the disk or cover element '2'1 is seated in 50 position to close the aperture I8, the end 29 `of the bar, or rather the hinge, is adapted to .be held by a catch .32 of the plate 4I'I lto retain the cover element in position 'for closing said aperture. By releasing the catch, the cover will be swung upwardly with the bar under the action of a spring 33 to permit removal of the contents of container l0. As these contents are depleted and the container collapses toward the bottom of the box Il, it will be evident that the cover element could not be swung back suiiciently to open fully the container because of the cylindrical shape of box Il and it may then be swung about the end 29 of the bar (as indicated in the dotted line position, Fig. l) to bring it a suicient height above the box wall to provide full access to the aperture I8.

In Figs. 7 to 12, a different form of closure is set forth, the same being of a more simple construction and embodying a pair of perforated plates or disks, the one plate 40 constituting the uppermost of the holding plates for the fold 4l of container 42 and a plate 43 the lowermost, as in the previous embodiment. This latter plate is provided with an aperture 44 and with an inwardly extending flange 45 to provide a seat for screen 46. Over the plate 40 is mounted a further perforated plate or disk 41, as by riveting the two plates together at the center 48 thereof with sufiicient play for angular movement of the one on the other about said rivet as a center. These plates 40 and 41 are provided with respective perforations 49 and 50, which are designed to register when the one plate is turned relatively to the other, as about the pivot 48, the limit of angular movement being determined, for example by a pin 5| extending upwardly from the plate 40 and into an arcuate slot 52 of the plate 41. In this embodiment the: box or receptacle 53 surrounding the container 42 is substantially square in cross-section.
